Measure out ¼ cup of oatmeal into a microwave safe bowl and then pour in ½ cup of water. If you're really hungry, or won't be eating for say five hours, double that. For school, I make ½ cup of oatmeal and 1 cup of water. Days when I'm home and have a morning snack, I go with the smaller amount.
Cook the oats according to the package directions. Mine say to cook them at half power for 3 minutes, but yours may say something different.
While the oats are still very hot, stir in a tablespoon or three of jam. Taste and add more jam if you think it's necessary. Repeat until the oats are as fruity and sweet as you like.
Cool Whip takes the whole oatmeal breakfast to a whole new level. I like to add about 3 large, overflowing tablespoons myself. I am currently out of Cool Whip, so I have been eating my oats without, and they're quite good that way, too.
